Subject: [iText-questions] Merging Problem
I am using iText 2.1.7 with JDK 1.4 to merge 2 PDF files. Below is the code I
used to merge the files. In the merged PDF (test.pdf), i don't see the contents
of the 1st PDF (choice2.pdf). Instead I see the "To view the full contents of
this document, you need a later version of the PDF viewer. You can
upgrade.....".
Why can't I see the contents of choice2.pdf in the merged test.pdf??
public static void main(String[] args)
{
String fileOne = "AcroForm.pdf";
String fileOne1 = "choice2.pdf";
String mergedFileLocation = test.pdf";
String filesTobeMerges[] = new String[] {fileOne, fileOne1 };
mergeMyFiles(filesTobeMerges, mergedFileLocation);
}
public static void mergeMyFiles(String filesToBeMerged[],
String mergedFileLocation) {
System.out.println("Starting To Merge Files...");
System.out.println("Total Number Of Files To Be
Merged..."+filesToBeMerged.length+"\n");
try {
int pageOffset = 0;
ArrayList masterBookMarkList = new ArrayList();
int fileIndex = 0;
String outFile = mergedFileLocation;
Document document = null;
PdfCopy writer = null;
PdfReader reader = null;
for (fileIndex = 0; fileIndex < filesToBeMerged.length;
fileIndex++) {
/**
* Create a reader for the file that we are reading
*/
reader = new PdfReader(filesToBeMerged[fileIndex]);
System.out.println("Reading File
-"+filesToBeMerged[fileIndex]);
/**
* Replace all the local named links with the actual
destinations.
*/
reader.consolidateNamedDestinations();
/**

int totalPages = reader.getNumberOfPages();

System.out.println("Checking for bookmarks...");

masterBookMarkList.addAll(bookmarks);
System.out.println("Bookmarks found and storing...");

}
